You'd be a Freakin moron not too supplement this. Essential minerals, No side effects, increases your Tes levels by up to 30% if used properly and promotes deep sleep???why the hell not, its inexpensive, wonderful product. If you take a calcium supplement take it in the mornings-afternoon and take your zma evening-night time in between meals and 45-60 minutes before bed time and you will sleep like a baby on morphine.
